(54) Vehicle diagnosis system


(57) A vehicle diagnosis system is configured to instruct vehicle operations required to finish a diagnosis without any increase in the storage capacity of an on-vehicle electronic control unit (31). When a repair person requests results of a self-diagnosis of a vehicle (30) executed by an ECU (31) using a diagnosis terminal (21), a management server (10) acquires instruction texts for the vehicle operations required to finish the diagnosis from a by-type diagnosis process database (11) at a remote management station (C) and causes the diagnosis terminal (21) to display the texts. The repair person operates the vehicle (30) according to the instruction texts displayed on the diagnosis terminal (21) to finish the self-diagnosis for which the request for diagnosis results has been made.
